To all whom it mag/concern.

Be it known that LJXLVA H. GAVEN, a citizen of the United States, residing at Youngwood, in the county of Vestmord land and State of Pennsylvania, have in-. vented a new and useful Trolley-Switch, of;

which the following is a specification.

The presentinvention relates to improvements in trolley switches, thefiparticular l0 switch being adapted to be used in connection with the signaling device and switch controlling mechanism as particularly setforth in my co-pending application filed December 17, 1913, Serial No. 807,296, one object of the present invention, being the provision of means adapted to be connected .to an over-head trolley wire, and supported so that a circuitfor energizing signal controlling solenoids or electromagnets may be closed by a passing trolley wheel so that the current from. the overhead trolley wire may be properlydistributed from said trolley wire to said solenoid, and as particularly set forth in the above copending application.

Avfurther object of the present invention,- is the provision of a device which willbe' protected from "sleet and snow, and which will properly house resilient contact members which are disposed upon each side of the trolley wire, and in a positionto engage oppositefaces of a passing trolley wheel to form the desired contact therebetween so that. current from the trolley will be cfausedto pass through the wheel to such contact plates and be distributed therefrom to the desired point.

With the foregoing and other'objects in view which will appear as the description proceeds, the invention I'ESldGS 1n the com- 'bination and arrangement of parts and in the details of constructionhereinafter described and claimed, it being understood that changes in the precise embodiment of,"

the invention herein disclosed can be made within the scope of whatis claimed without departing from the spirit of the invention;

In the drawings-Figure 1 is a bottom plan view of the present device, dotted lines illustrating the position of a trolley wheel when entering the same and justprevious to theengagement' of theresilient contacts thereof. Fig. 2 is a sectiontaken on line 2-2 of Fig. 1. Fig. 3 is an endview lookingffI'Om the left as viewed in Figs. land 2.

the mounting of the free endof one of the resilientcontactsh Referring to the drawings, the numeral screws, 3 to depend within the casing formed by the top wall 4 and the depending aprons 5 and 6 thereof, a'strip: 3" of {insulation being interposed betweenithe respective trolley wire supporting'members 2 and the under side of the top 4 of the casing or hood. This casing, as clearlyillustra ted in Fig. 3, is an inverted U-shaped member and .therefore provides a hood open at both ends for preventing sleet, rain or snow from effecting iclhe dportion of the trolley wire within the oc r . The supports 4 properlyhold the housing supported and assist in maintaining the over-head trolley above the track.

Connected to the inner sides of the respective walls 5 and'6 arethe strips 77 of insulation, these ,jbeing disposed for instance, at the entrance end of thehood while 1 in the desired position strips 8+8 of insulation. By this means, as will presently appear, the two resilient switch or contact plates l010 supported and insulated from the, hood or casing.

p Two metal plates 9 and 9. are connected paratus as particularly set forth in my copending application, and the connection 13 insuring the proper distribution of the current from theplate 10, should the plate 10' fail when the trolley wheel N has its opposite faces engaged by the inner faces respectively of the plates 10-10, the resilient mounting of said plates permitting the proper engagement or contact of the wheel upon opposite sides so asv to cause the wheel are properly disposed-at the exit end thereof are the two to close the between the trolley 1 and either one or both of the plates 10-lO".

Under normal conditions, the circuit is opened between the plates 10-10, and-is only closed when the trolley Wheel W carried by the pole.
